Dominque Ansel will be debuting the creation at SXSW this weekend. He said this to Eater:

The inspiration for the dessert — a chocolate cookie "glass" containing a "shot" of milk — came after Ansel tried his first Oreo "a few weeks ago" and was encouraged to eat it with milk, which is not "a natural combination in French culture."

Figuring that "if everyone was drinking milk with cookies, you might as well make a dessert that allows them both to be combined," Ansel has created a chocolate chip cookie recipe that "stayed crispy and moist in parts" even as it held milk.
